EMC Test Report
Reference No.: NK2EE 267.EMS
11. Radio-frequency, Electromagnetic Field Keyed Carrier Immunity test (ENV 50204)
11.1 Test criteria and test procedure
Operating environment;
Temperature:
20 ℃
Relative Humidity:
40 %
The tests were performed at 3m distance in an anechoic chamber.
For floor-standing equipment, the EuT was standing on the floor, isolated from the ferrite core.
For tabletop equipment, the EuT was located on a wooden table 0.8m above the floor.
The EuT was exposed to the field from different angles, normally 0。, 90。,180。,270。 and 360。
and at both horizontal and vertical polarization (antenna height 1.5m).
A signal level of 3V/m, 50% PM modulated with a 200Hz was applied in the frequency range
895 - 905MHz.
